Sprint Nextel has launched the Motorola i615, replacing the Motorola i605. The i615 builds on the i605 by adding a more rugged exterior. However, there are no significant feature enhancements on the i615 beyond a redesigned keypad.
In addition, the i615 has a lower standby battery time, indicating that Motorola is using a less expensive battery in the device (though both are rated the same ampere-hours).Nextel Motorola i615 Product Page
